Inverter not putting out 110V

I have a Vector Maxx-SST VEC062 700w-1000peak inverter that is now only putting out 94v. Input is 13.6v, short (16")8g leads to the converter and batteries are good, all on and connected to shore. Measured with my Fluke True RMS meter, it will go up to 98v with a load (hair dryer on low). Is there any adjustment for the output volts?

    First of all it looks like your meter, or user, has a problem.
    Your battery(s) are 12.6 to 12.7 volts when fully charged, so a 13.7v input from battery to inverter is impossible. That could mean that your AC output voltage reading was also incorrect.

    Did you use the clamp-meter to check the amps going from battery to inverter under load? Was it anywhere near the expected current for the hair-drier?

    I would start by replacing the battery in the Fluke and checking against your stick-house 120v ac outlet. Also check your house-battery voltage now that it had a load on it.
